..., measurements of residual stresses, and various wear and corrosion tests. This paper will represent microstructural and microhardness analyses of the thin surface layer after laser remelting of nodular cast iron 500-7. Particular attention is paid to fatigue crack initiation and propagation tests. Crack...

...V. A. Pozdnyakov; O. V. Borisov; V. P. Filippova A new method of simulation of residual stresses in ribbons of amorphous metallic alloys is proposed. The model considers the total deformation remaining in an amorphous metallic alloy during the quenching from liquid state to be the sum of elastic...

... cracks. The model simulates multiple ball impacts with a fatigue spall’s edge in a 208 size ball bearing operating at 10,000 rpm. Ball impacts are shown to cause severe plastic deformation within the spall edge and induce tensile residual stresses. The finite element results are supported by X-ray...

... stresses, residual stresses Introduction and Background Fastener joints, in which single or double lap sheets with circular holes are connected via cylindrical pins, have a broad range of applications in many engineering structures. These joints must also be considered a potential failure location due...

This paper uses elastic-plastic, finite-element analyses to study the influence of the tensile residual stresses induced by compression precracking on simulated crack growth under constant-amplitude...

... significant compressive plastic strains. The resulting tensile residual stresses in the corner region significantly reduce the fatigue strength in some design applications. Sections cut from CFRHSs with two different wall thicknesses were studied using distortion fatigue loading and using X-ray diffraction...

...WT Fujimoto First generation crack formation and crack growth predictive approaches for cold-worked holes—based on the growth of a single noninteracting crack in a stationary residual stress field—fail to account fully for the physical mechanisms by which cracks form and grow from cold-worked holes...

...A Atre; WS Johnson Multiple site damage (MSD) in aircraft structures can be defined by the presence of numerous minute cracks arising at different locations such as rivet holes in lap joints. One source of initiation can be due to residual stresses induced in the lap joints during the riveting...

...L Edwards; ME Fitzpatrick; PE Irving; I Sinclair; X Zhang; D Yapp Although residual stress in welded structures and components has long been known to have an effect on their fatigue performance, access to reliable, spatially accurate residual stress field data has been limited. Recent advances...
